Yeah, there are a few that still have the old 390. Nevertheless, the 560W is quite real. I've seen it with my own two beedy eyes. See the link below. Hope somebody has one they're willing to part with! :/

Do the math...
The 390 Watt Powersupply is probably more than you will ever need.
I ran my 9600 Mach 5 350, with all PCI slots full, All drive slots full, an XLR8 500 MHZ Processor upgrade card, ( Overclocked to 520Mhz. )and 2 LVD drives on the bottom mounting plate.
Add up what the devices you want to run will draw, and I can assure you it is nowhere near what the 390 Watt unit can handle.

Uh, just because it says so on a couple of Apple tech pages, don't make it so for sure. I have a 9600/350. It's got a 390W. The two other 9600/350's I've looked at recently had 390W's. UnPhotoshopdoctored picture please. Proof's in the pudding. Yes, it would be nice to lay this question to rest.

It's on www.everymac.com, www.lowendmac.com and Apple's website. Why in the world whould they make something like this up? I agree though, it would be nice to see if somebody actually had one and we could put the question to rest.

It's on those websites because they got their info from the Apple specs too. One typo at the beginning leads to a cascade of errors down the line creating a myth. I'm not saying they don't exist. I'm just saying I've never seen any proof that they do. I await with abated breath for the pic (is that supposed to be abated breath or baited breath, I should know these cliches).

I have a 600 Watt in my 9600/200 via a hack using an ATX unit and a digital IC. Don't know if I NEED that much but it cost me $50 to set it up and at the time OEM 390's went for much more. Working great for over a year with no probs. Don't know if its OSX related but can't use any more than 4 PCI slots or it locks at bootup. Anyone have any Idea why??

Unless the processor upgrade is designed to allow for the 3 lower slots, it should only use 3 upper slots. If its using 4 slots, I would assume you have a 6 slot upgrade. Maybe you have a mobo problem. Some PCI devices don't make nice next to each-other. Try changing the order.

Don't believe everything you see on the internet. There never was a 560w power supply. If there are units out there that say 560w on them, then they are misprints on the labels and not the real deal. No computer back in the 8600/9600 era required that much power so it would be pointless to make one that powerful back then and it would have been very expensive as it would have been unique to the 8600/9600. The much desired Mirror Drive Door power supply is only 400 watts and wasn't introduced until 5 years later. There is no way that you can ever use 560w of power on a 8600/9600 using the devices that were available at the time.

I have owned a 560 watt power supply, it was a working pull out of a video editing rig. I purchased it at the MIT Flea Market in October of 2002. I wish I had thought to keep it so I could be the guy that finally puts to rest the myth of whether or not they exist. I suppose if I still had it and posted pics of it it wouldn't be enough to convince people that it's real, I'd probably have to grab it by the leads and smash someone in the head to convince them it was real. My point in quoting this is to ask "Why do you think they are misprints?" I had a Sun tower that took a 1kw power supply, the machine was huge, it weighed ~200lbs, and it had 4 20mhz ross processors. Do you doubt that it exists? Did it not need that power?

Perhaps you don't recall the costs of the 8600/9600's. They went upwards of $5,000 for a well dressed machine. Does that sound like something that wouldn't justify an expensive component?

There are many machines that have power supplies that output more than the machines need, this isn't so much to provide power to many peripherals, but to keep one component from pulling too much power and short volting something else.

Unfortunately, there are a lot of people who will swear they had lunch with Elvis yesterday too. My father swore up and down that he saw a long-time-believed-extinct Ivory Billed Woodpecker one day when he was out hunting by himself in the Louisiana bayou. He didn't shoot it, he said, because then everyone would have come down on him for shooting the last Ivory Billed Woodpecker. So there you go.

I'm not saying I don't believe you anymore than I didn't believe my father--no way to know, just take it on faith. Others in the family have made particular claims which require even more faith--a LOT of faith.

I just checked the two 9600 powersupplies I have. Neither say Apple anywhere that I can see, nor have the apple logo. Both are made by Delta Electronics, so maybe there's no way to prove for sure that any 9600's shipped with 560w powersupplies anyway, unless someone were to get the actual bill of lading listing it, or some such proof, and lacking that, the Apple documents mentioned above may be the only proof that has survived. Lacking some marking designating one was made for Apple, then the claim can always be made that someone could have rigged up a third party PS and put it in a 9600.

Video production would certainly be the most likely market for an especially powered 9600, though. I mean, you can imagine how many video and film producers would have loved to have been seen with a souped-up 9600--with power beyond it's possible need--in the backseat of their revving Ferrari as they did 30mph down Hollywood Boulevard. The aspiring starletts trying to catch up with them in their Porsche's would have just whistled and crooned. And then, of course, there may have also been an unspecified market for overpowered 9600's to run the government's black helicopters. I, for one, am going to take your witness testimony as proof, since like others have said, it wouldn't make a lot of sense to rig up one anyway, so it must have been real. And after all, the 9600 was designed and produced when Steve Jobs had long since left the building, and just before his glittery return, so it was brought into existence during Apple's loony days when anything was possible. After J's return, the days weren't loony anymore, they were "different."
